PINTLE ATTACHMENT FOR lVfACHINE ELEMENTS.

Application filed February 13, 1915.

certain new and useful Improvements in Pintle Attachments for MachineElements;

and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its object to provide a simple, economical andeffective fulcrum anchor for oscillatory machine elements, the samebeing especially applicable to fly-wheel governors.

The construction and arrangement of my invention are such that themachine work ordinarily necessary for fitting the fulcrum ele ment iseliminated, it being usual in the type of governors to which myinvention especially refers, to cast cars from the spokes of thefly-wheel, which ears are then bored for the reception of a fulcrum pin.The boring operation, owing to the position of the ears and the varioussizes of fly-wheels, thus causes considerable skill and expenditure oftime in completing the operation with tools of ordinary construction. Itis obvious, however, thatmy peculiar arrangement of attaching the anchorpin employed in the construction of various machine elements willovercome the above objectionable features as the parts canall beassembled without recourse to machining or fine adjustment.

' With the above objects in view the in' vention consists in certainpeculiarities of construction and combination of parts as hereinafterset forth with reference to the accompanying drawings and subsequentlyclaimed.

In the drawings Figure 1 represents an elevation of a fiy-wheel providedwith a governor fulcrum pin attached in accordance with my invention,parts being broken away and parts in section, as indicated by lines l1of Figs. 2 and 3; Fig. 2, a detailed face view of a fragment of theflywheel, partly in section, as indicated by line 22 of Fig. 1; Fig. 3,another detailed sectional view, the same being indicated by line 3-3 ofFig. 2, and Fig. 4, an enlarged detailed sectional view showing theanchor-pin construction, the same being indicated by line 4-4 of Fig. 2.

While I have shown an exemplification of Specification of LettersPatent.

my invention associated with a governorcontrolled fiy-wheel, it isobvious that the saine'may be employed in connection with variousmachine elements.

Referring by characters to the drawings,

1 represents a fragment of a bed carrying a ournal-box, in which 15mounted a shaft 2 having keyed thereto a fly-wheel 3 and loosely mountedthereon a sleeve 4, which sleeve is adapted to control a knock-off lever5 that constitutes part of a valve tripping mechanism for an internalcombustion engine, not shown. The sleeve is longitudinally. shifted uponthe shaft by a spring-controlled governor arm 6, which governor arm isloosely fulcrumed upon a pivot-pin 7 that is attached to companionspokes 3' of the fly-wheel, the same constituting a base member. Thecompanion spokes are cast with raised pads 8, 8, which are spaced apartto form a socket for the apertured hub 6 of the governor arm, the samebeing, as previously stated, loosely mounted upon the fulcrum pin 7. Thefulcrum pin, as shown, is seated in interrupted or companion V-shapedgrooves 9, which grooves intersect circular apertures 10 that extendthrough the pads and fly-wheel arms. These apertures, owing to theirconvenient and accessible alinement, may be bored in some instances, orcored as conditions warrant. The pivot-pin, which is circularincross-section, is-provided with squared ends that are alined with theinner opposite walls of the apertures 10, whereby said apertures presentunobstructed passages for bolt elements 11, having squared shanks 11,faces of which abut the squared ends of the pivot-pins, as shown. Thebolt elements are also provided with suitable heads 11, which, as bestshown in Fig. 1, overlap and impinge the circular faces of the pivot-pinends and, owing to the fact that the squared ends of said pivot-pinsalso abut the squared shanks 11 of the bolt elements, it will beobserved that said bolt elements are held against twisting in theirretaining apertures when they are drawn up by the usual binding washersand nuts 13, which elements abutthe opposite faces of the spokes, asbest shown in Fig. 3. Thus it is apparent that the V-shaped groove seats9 for the pivot-pin, in conjunction with the bolt-heads 11, form athree-point bearing for said pivot-pin, whereby the latter is firmlygripped at its ends and is thus held against twisting. This departingfrom the spirit of my invention and attention is also directed to thefact that the anchor 'pin projects slightly above the'faces of the pads,whereby a positive firm grip is insured as there is suflicient clearancebetween the bolt-heads and said pad faces to permit all of the drawnecessarj to clamp the parts tightly to the surfaces engaged by saidpin. It is also ap parent that, while I have'shown bolt elementsseparable from both ends of the pin 7, I may, in some instances, formone of the bolt elements as a right-angle continuation of the pin, foraccomplishing the same result and the invention may be carried out byvarious other modified forms, the essential feature being the groovedseat with a bolt element for clamping the pivot-pin firmly within itsseat.

7 I claim; 7 1 1 1. An anchor-pin attaching means comprising a basehaving an aperture therein,

and a grooved seat intersecting the aperture,

a pivot-pin seated within the groove, a confining bolt member for thepin extending through the aperture, and a nut engaging the bolt'end,whereby the pivot-pin is, caused to grippingly engage the seat groove.

' 2. An anchor-pin attaching means comprising a base having companionapertures therein, an interrupted groove intersecting the apertures, apivot-pin seated within the groove terminating at the apertures, andheaded confining bolts for engagement with the pin ends extendingthrough the apertures. r 5

3. An anchor-pin attaching means comprising a base having companioncircular apertures therein, an interrupted groove intersecting theapertures, apivot-pin seated within the groove terminating at theapertures, and headed confining bolts for engagement with the pin endsextending through the apertures, the bolts being provided with squaredshanks, faces of which abut the ends of the pin, and an arm looselymounted upon the pin between the grooves. 1

at. An anchor-pin attaching means com-V prising a base having anaperture therein, a V-shaped groove intersecting the aperture, apivot-pin seated within the groove, a: confining bolt member for the pinextending through the aperture,'and, a nut engaging the bolt end,whereby the pivot-pin is caused to grippingly engage the-seat groove.

5. An anchor-pin attaching means'comprising a base having companionapertures therein,interrupted V-ShZIPGd grooves'intersecting F, theapertures, a circular pivot-pin seated within the grooves, confiningbolts having heads-for engagement with the ends of the pivot-pinextending through the apertures, and securing nuts for saidbolts. v V

In testimony that I claim the foregoing I have hereunto set my hand atPort Washington, in the county of Ozaulree and State of' Wiscon'sin, inth'epre'sence of two witnesses.
